Abstract
A new, inexpensive and simple method for agglutinating fine powder on bare particles or cores has been developed. This process allows to coat various kinds of cores with different types of coatings (metal, ceramic, cermet, polymer, etc.). In this work, the advantages of the technique are exemplified by a specific application: the fabrication of wear-resistant composites. Thick iron powder coatings were agglutinated on WC-Co particles. These coated particles were compacted by powder metallurgy techniques and thereafter the compact was infiltrated with copper in order to make them wear-resistant composite parts. The use of coated particles leads to major improvements in the WC-Co particle dispersion. It also provides a material suitable for feeding commercial compacting presses and thus greatiy facilitates the production of composites on an industrial scale.
